IMPROVEMENTS IN NEUTRON DETECTORS

Patent ·
OSTI ID:4227672
A gas-flow neutron flux measurement instrument is described. Fissionnble material of 4 mu thickness or less is exposed to the flux and fission fragments emitted are swept by a gas (air, CO/sub 2/, N/sub 2/) to a beta o- gamma counter. The gas conduits, of Al to prevent electrostatic effects, allow the counter to be remotely located to avoid gamma radiation mixed with the neutrons. (T.R.H.)
